Just to clarify:

The "dokidoki" in the title signifies "nervous", "anticipating", "lovestruck", and probably a few other adjectives, all rolled into one. I opted to keep it as so the title wouldn't be too long.

Yeah. Kids. Circuits.

Wow, if I had one of those when I was a kid maybe I wouldn't have flopped that part of science class. S
Saki's face in the 4th panel is hilarious.
